Hi all with temps this past couple weeks going 8 below zero in my area for first time in nearly a decade 2 of my customers had major problems with there dry pipe sprinkler systems because a drain moisture accumulator which is on the end of the dry pipe systems was not being properly checked and drained and moisture accumulated in the drain and froze breaking the pipe and sending water thruout the system and flooding my clients property. becuse the accumulators were in an unheated part of building. normally we never have to worry about dry pipe systems just where the water sits at the main valve but the extreme temps have proved otherwise. do your customers a favor and let them know they need to make sure this accumulator valve needs serviced when system is inspected.
